Although we're expecting world+dog to launch G92-based 8800 GTS 512MB cards today, so far it seems that only Gigabyte and Leadtek have their product pages online. We had a look at all the other usual suspects, but it seems that they haven't gotten around to updating their Websites yet.
Gigabyte doesn't list any specifications in terms of clock speeds for their card, and in general there isn't a lot of information at all on the product page, apart from the fact that they are still shipping Neverwinter Nights 2 as their game bundle. You can find the product page here.
Leadtek provides a bit more information, as their card will have the GPU clocked at 690MHz with the memory at 1,940MHz, although no Shader clocks were mentioned. This is faster than the reference clock speed for the GPU and we can't wait to see how fast companies such as XFX will take this card. Oddly enough, a GPU clock speed of 650MHz is also mentioned for this card.
But get this: Gigabyte isn't the only company bundling Neverwinter Nights 2, as this is exactly the same game that Leadtek is bundling. We can only assume that this game is being sold for pennies as a bundled package. You can find the Leadtek product page here
